Finder 66.82.9.048.1300 – 66 Series Power relays

Why Choose the Finder 66.82.9.048.1300 Power Relay?

The Finder 66.82.9.048.1300 is an industrial electromagnetic power relay from the Finder 66 Series, designed for high-current electrical switching in industrial machinery, automation systems and OEM control equipment. Its part-number configuration identifies a 48 V DC coil, two normally open contacts (DPST-NO) and silver nickel (AgNi) contact material.

The 66.82 flange-mounted design features Faston 250 quick-connect terminals, making it suitable for equipment where a relay must be mechanically secured to a panel or chassis rather than soldered directly onto a printed circuit board. The detachable connections also simplify installation, servicing and replacement when used with compatible terminals.

With a 30 A rated contact platform, reinforced coil-to-contact insulation and two normally open switching circuits, the Finder 66.82.9.048.1300 offers a practical solution for controlling suitable electrical loads from a DC control supply. The AgNi contact option should be distinguished from the AgSnO2 versions in the same series, as contact material can affect switching performance and peak-current ratings.

Key Advantages

• 48 V DC coil designation for compatible DC control circuits.
• 2 NO (DPST-NO) contacts for simultaneous switching of two independent load circuits.
• 30 A rated contact platform for demanding industrial power control applications.
• Silver nickel (AgNi) contacts provide a cadmium-free contact-material option.
• Top flange mounting supports secure mechanical installation.
• Faston 250 quick-connect terminals simplify wiring and maintenance.
• Reinforced insulation between the coil and contact circuits.
• 8 mm creepage and clearance distances between coil and contacts.
• 6 kV coil-to-contact impulse withstand voltage in the Finder 66 Series insulation design.
• Two-pole normally open operation provides straightforward load control from a single coil.
• Suitable for industrial automation, heating equipment, machinery and OEM electrical assemblies.

• Faston 250 terminals measuring 6.3 × 0.8 mm.
• Reinforced coil-to-contact insulation.
• Standard environmental protection option.
• Non-latching electromagnetic operation.
• Designed for integration into industrial electrical control equipment.

Specification note: The 48 V DC coil designation is identifiable from the part number, but 48 V DC is not included in the standard DC coil voltage list in the published Finder 66 Series datasheet. The exact coil availability, operating voltage range, resistance and consumption for 66.82.9.048.1300 should therefore be confirmed with Finder before ordering or finalising an equipment design.

Reliable Two-Pole Switching for Industrial Control Systems

The Finder 66.82.9.048.1300 uses an electromagnetic coil to operate two normally open power contacts. When the appropriate DC voltage is applied to the coil, both contacts close and allow current to flow through their respective load circuits. When the coil supply is removed, the contacts return to their normally open positions.

The 1300 contact configuration identifies the combination of AgNi contact material, two normally open contacts and a standard enclosure version. This is distinct from the 4300 configuration, which uses silver tin oxide contact material. Although both are available within the 66 Series contact system, their switching characteristics should not be treated as identical, particularly when considering peak current and demanding load conditions.

The 66.82 flange-mounted housing is designed for industrial equipment where secure mechanical fixing and detachable electrical connections are preferred. Its Faston 250 terminals provide a convenient wiring interface, while reinforced insulation between the coil and contacts supports electrical separation in appropriately designed control circuits.

As with all industrial power relays, the suitability of this model depends on the connected load type, operating voltage, switching frequency, inrush current and installation conditions. The 30 A contact rating should not be interpreted as a universal rating for every motor, inductive or capacitive load.
